WEATHER STRIP Filed Jan. 18, 1939 Invert or. am 6 Patented Apr. 9, 1940 UNITED STATES PATENT OFFICE.

David C. Bailey, Amesbury, Mass.

Application January 18, 1939, Serial No. 251.543 4 Claims. (Cl. 20-69) This invention relates to certain improvements in weather strips, which are primarily designed for use in automobile bodies where an ornamental finish is not required, and has for its objectsto 5 provide a wea/ther strip which may' be manufactured at comparatively small expense, which is readily bendable in any direction and is adapted to be readily applied to a projecting flange, or

Y edge portion, and when applied to be securely l0 held in position and effectively seal a joint be- "tween two parts, orto provide a cushion for a window glass, when required.

I accomplish these objects by providing a weather strip having a core which, insome respects, is similar to the core disclosed in my prior Patent No. 2,102,936 of December 21, 1937, in that it is formed of thin corrugated sheet metal, said core being bent transversely into a form which permits ready application to a projecting flange' or edge portion and which is covered by a fabric having a tufted portion incorporated therein and located on the face side of the strip in position for engagement with the body portion or window glass between which and the part to which the g5 strip is attached there is 'a joint which is to be sealed.

For a more complete disclosure of my present invention reference is now made to the following specification in connection with the accompanying drawing in which:

Fig. 1 is a combined/sectional and'perspective view of a weather' strip embodying my invention.

Fig. 2 is a sectional view illustrating an application thereof to an automobile part.`

Fig. 3 is a sectional viewA similar to Fig. 2 illustrating a modified form of connection of the strip with a garnish molding, or4 other body member.

Weather strips are employed in various relations in automobile bodies for the purpose of ob- 40 structing drafts or preventing the entrance of water, and also to cushion window glass and provide a tight joint between the glass and a body' 'Ihe core is bent transversely to form a middle portion I2 of approximately the same width internally as the thickness of .the flange a, b, an outer side portion I3 which is of no greater width than the height of said flange and an inner side portion I0 which is of somewhat greater width f than the outer side portion I3.

' The entire inner and outer surface of the core is covered by a strip of ltextile. fabric I5, which is adhesively connected thereto throughout its en- 10 tire surface; The fabric is provided with a longitudinally extending cushioning rib I6 on' the middle vof the wider side portion of the core, said rib being composed of vertical pile which are secured to the fabric in upright position, as indicated in l5 Figs. 1 and 2.

The core is so constructed that, with the lining on its inner sides, it will fit tightly on the flange a, b, so that considerable force is required to force it onto the ange a, b until its middle portion n engages the tcp of the flange. The weather strip will thus be attached to the flange by frictional engagement. A weather strip will be applied to both iianges, as show in Fig. 2. The fact that the core is corrugated greatly increases its strength u' and holding power. The fabric covering is securely clamped between the sides of the core and the flange on which the strip is mounted, so that it will not become detached'from the rcore even if the adhesive connection is imperfect. The strip is adapted to be bent either in the Vplane of its sidesl or laterally thereof, so that it may be readily conformed to any requirement. z

In use the tufted portion I6 engages the glass or other part, as shown in Fig. 2l and provides a suitable cushion therefor and at the same time tightly closes the joint between the two adJacen'tly disposed parts.

In Fig. 3, a method of connecting the weather strip to a garnish molding is illustrated, in which the moldings e, have flanges f, the edge portions of which are hemmed or bent reversely to form thickened edge portions 9'.

For use in this connection the weather strip I8 is constructed as already described, the core 5 being constructed to fit tightly onto the flange of the molding. The outer portion of the core, however, extends somewhat beyond the thickened portion of the flange, when in this position, and its 4edge portion Il is bent inward, after the 5o strip has been forced into position on the flange, so that the strip is securely locked to the flange. as shown in Fig. 3. With either of the above described constructions th'e use of staples or other small fasteners ular thereto, and a fabric covering connected to the outer and inner surfaces oi' said c ore and having a cushioning rib thereon extending longitudinally of the outer side of one of said side portions.

2. A weather strip having a core consisting of a strip of thin sheet metal having closely arranged transverse corrugations extending from edge to edge thereof, said core being bent to form a longitudinal intermediate portion and two side portions of unequal width disposed approximately perpendicular thereto, and a fabric covering connected to the outer and inner surfaces of said core and having a cushioning rib thereon extending longitudinally of the outer side-of the wider of said side portions.

ranged transverse corrugations extending from y edge to edge thereof, said core being bent to form a longitudinal intermediate portion and two side portions approximately perpendicular thereto, and a fabric covering extending from the inner side of each side portion of the core and about the edges and outer sides thereof and adhesively connected thereto, and said fabric having a cushioning rib extending longitudinally on the outer side of one of said side portions.

4. In combination with a body molding having a flange provided with a thickened edge portion, a weather strip of thin sheet metal having closely arranged transverse corrugatlons extending from edge to edge thereof, said core being bent in U- form and adapted to iit onto said flange, a fabric covering on the surface of said core, said covering having a longitudinal cushioning rib on one of the side portions of the core and the opposite side portion of the core being bent inward beyond the thickened 4edge portion of the ange to lock the strip thereto.
